Indicating repetitions at a UE in an NTN includes decoding a communication indicating a timing relationship value associated with a distance between a serving satellite and a farthest UE in the NTN. A PRACH communication is encoded for transmission. The PRACH communication includes an indication of a number of PRACH repetitions determined based on the timing relationship value. A RAR including an uplink (UL) grant corresponding to the UE and an indication of a number of RAR repetitions is decoded. The number of RAR repetitions is determined based on the timing relationship value. A PUSCH communication including an indication of a number of PUSCH repetitions is encoded. The number of PUSCH repetitions is determined based on the timing relationship value. A content resolution communication including an indication of a number of content resolution repetitions is decoded. The number of content resolution repetitions is determined based on the timing relationship value.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the timing relationship value is broadcast via a system information block (SIB).
3. The method of claim 1, wherein the number of PRACH repetitions is further determined based on a comparison of the timing relationship value and a PRACH timing relationship value threshold.
4. The method of claim 1, wherein the number of RAR repetitions is further determined based on a comparison of the timing relationship value and a RAR timing relationship value threshold.
5. The method of claim 1, wherein a number of UL scheduling repetitions is determined based on a comparison of the timing relationship value and a UL scheduling timing relationship value threshold.
6. The method of claim 1, wherein the number of content resolution repetitions is further determined based on a comparison of the timing relationship value and a content resolution timing relationship value threshold.
7. The method of claim 1, wherein the number of PRACH repetitions, the number of RAR repetitions, a number of UL scheduling repetitions, and the number of content resolution repetitions are further determined based on a comparison of the timing relationship value and a single timing relationship value threshold.
8. The method of claim 7, wherein the single timing relationship value threshold comprises a first value when the NTN is associated with a geosynchronous equatorial orbit (GEO) satellite scenario and a second value when the NTN is associated with a low Earth orbit (LEO) satellite scenario.
9. The method of claim 7, wherein the single timing relationship value threshold is associated with a number of slots.
10. The method of claim 1, further comprising triggering inter-slot frequency hopping based on the timing relationship value, inter-slot frequency hopping being applied to at least one of the PRACH communication, the PUSCH communication, the RAR, or the content resolution communication.
11. The method of claim 10, wherein the frequency hopping is defined per slot or per bundling window.
13. The method of claim 12, wherein the number of PRACH repetitions are further determined based on a comparison of the timing relationship and a PRACH timing relationship value threshold and the RAR repetitions are further determined based on a comparison of the timing relationship value and a RAR timing relationship value threshold.
14. The method of claim 12, wherein the number of PRACH repetitions and the number of RAR repetitions are further determined based on a comparison of the timing relationship value and a single timing relationship value threshold.
15. The method of claim 14, wherein the single timing relationship value threshold comprises a first value when in the NTN is associated with a geosynchronous equatorial orbit (GEO) satellite scenario and a second value when the NTN is associated with a low Earth orbit (LEO) satellite scenario.
16. The method of claim 12, further comprising triggering inter-slot frequency hopping based on the timing relationship value, inter-slot frequency hopping being applied to at least one of the PRACH communication, the PUSCH communication, the RAR, or the content resolution communication.
18. The method of claim 17, further comprising configuring more than one PDSCH repetition value in the SPS configuration, and determining which of the more than one PDSCH repetition value is used based on the timing relationship value.
19. The method of claim 17, wherein the configuration type comprises the SPS configuration, the SPS configuration including multiple (MCS) tables, wherein determining which of the multiple MCS tables to use is based on the timing relationship value.
20. The method of claim 17, wherein the configuration type comprises the configured grant configuration, the configured grant configuration including multiple configured PUSCH repetition values, wherein determining which one of the multiple configured PUSCH repetition values to use is based on the timing relationship value.
